Some Useful Network Commands For Windows DOS
Windows has a whole array of helpful command line tools for configuring and testing Internet and LAN connections. The following is a list of useful network commands that can be used from the command prompt. A lot of these commands are intended for administrating a network, but they are great for savvy home users as well. All of the tools are run by opening a Command window and entering the appropriate command. Go to Start-Run and enter “cmd” to open a Command window.
- net – Used to start, stop and view networking operations.
- ipconfig – Displays the IP Address and other TCP/IP information on your system.
- netstat – Returns protocol statistics and current TCP/IP connections.
- hostname – Displays the Microsoft networking computer name.
- lpq – Displays the print queue status of an LPD printer.
- ping – Verify the connectivity or a host across a network.
- nbtstat – Returns protocol statistics and current TCP/IP connections.
- ipxroute – Displays and modifies IPX routing tables.
- route – Manipulates TCP/IP routing information
- tracert – Displays route taken by an ICMP to a remote host.
- finger – Displays information about the user
- arp – Displays or modifies information in the ARP (Address Resolution Protocol) cache
- getmac – Lists the MAC (Media Access Control) Address on the computer network interfaces
Add /? to the command will provide more information e.g. ipconfig show more information about ipconfig command.
Some Applications:
- Display Connection Configuration: ipconfig /all
- Display DNS Cache Info Configuration: ipconfig /displaydns
- Clear DNS Cache: ipconfig /flushdns
- Release All IP Address Connections: ipconfig /release
- Renew All IP Address Connections: ipconfig /renew
- Re-Register the DNS connections: ipconfig /registerdns
- Change/Modify DHCP Class ID: ipconfig /setclassid
- Network Connections: control netconnections
- Network Setup Wizard: netsetup.cpl
- Test Connectivity: ping www.tomstricks.com
- Trace IP address Route: tracert
- Displays the TCP/IP protocol sessions: netstat
- Display Local Route: route
- Display Resolved MAC Addresses: arp
- Display Name of Computer Currently on: hostname
- Display DHCP Class Information:ipconfig /showclassid
Notes:
- Some command-line tools require the user to have administrator-level privileges on source and/or target computers.
- You must have the TCP/IP network protocol installed to use the TCP/IP utilities.
Windows 7 and HP Laserjet 1012 Driver not working
A HP Laserjet will not work with Windows 7. The followinf solution works well. If you vary the following method it will work for 32 bit if required.
Alright, I found the real fix for this so you can print at normal speed and not get the Pesonality Not Supported: PCL Error [For Advanced Users].
1. First off, go download HP LaserJet 1012 Host Based drivers.
64-bit:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=18972&prodSeriesId=377934&prodNameId=306510&
swEnvOID=2100&swLang=8&mode=2&taskId=135&swItem=lj-67501-1
32-bit:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=306510&prodTypeId=18972&prodSeriesId=377934&
swLang=8&taskId=135&swEnvOID=2093
2. Extract the driver.
3. Plug in and turn on your printer if you havent already.
4. Go to Start>Devices and Printers, and choose to add a printer
5. Choose to add a local printer
6. Choose Dot-4-usb printing support
7. Click Have Disk on the next window
8. Navigate to where you extracted the drivers, and choose the inf file
9. Choose the HP 1012 HB Driver
10. Follow the prompt till it installs the printer or what not
Now you may notice that it prints slow as heck, well no worries! To fix that do this.
1. Go to Start, right click Computer and choose Manage
2. Go to Device Manager
3. Find 1284.4 dot4usb Printing Support
4. Right click it and choose Update Driver
5. Choose Browse my computer for driver software.
6. Choose USB Virtual Printing Support
7. Follow the prompt, exit out of Device Manager
8. Go to Start>Devices and Printers
9. Right click HP 1012 HB, choose Printer Properties
10. Go to the Port Tab, find Virtual USB Printing Support (Not dot4) and check that.
11. Click Ok.
Alternate Method 1
NB:
- 1300 has proper driver for windows vista
- 1300 has same internals as 1015
- 1300 uses 'HP Univeral Printing PCL5/PCL5.1' system 5.0/5.1 - use 5.0 1015 is a pcl 5.0
Probable Causes of Soldering Iron Tip Failure
Probable Causes of Soldering Iron Tip Failure
There are many factors that influence soldering iron and tip life. Tips life will depend on proper maintenance, cleaning, temperature, tip configuration, and the jobs being done. Get the best performance from your iron and maximize tip life by following these simple suggestions and precautions. For soldering iron and tip care suggestions go to tipcare.htm.
- Make sure you have the correct amount of voltage in your line for your iron. Most irons are designed to handle slightly varying supply voltages but a consistently high line voltage will cause the iron to run hot and reduce tip life.
- The higher the tip temperature, the faster oxidation forms. Soldering at temperatures over 875º F causes your iron tip to oxidize twice as fast as soldering at 700º F. Adjust your soldering temperature to the minimum temperature needed to melt your solder and have it flow smoothly.
Alloy Tin ‰ Lead ‰ Solid to Liquid at Pasty Range 50/50 50 50 361º 421º 60º 60/40 60 40 361º 374º 13º 63/37 63 37 361º 361º 0º -
60/40 Solder: Composed of 60% tin and 40% lead, this solder melts at 374 ºF, but doesn't become completely solid until it cools to 361ºF. This means it has a "pasty range" or "working range" of 13 degrees.
-
50/50 Solder: This is composed of 50% tin and 50% lead. It is liquid at 421ºF, solid at 361ºF and has a pasty range of 60 degrees.
-
63/37 Solder: This solder is 63% tin and 37% lead. It becomes liquid at 361ºF, and solid at 361ºF, with a pasty or working range of 0 degrees. This solder is called a eutectic alloy which means at 361ºF, you can go instantly from solid to liquid to solid just by applying or removing the heat source.
-
Lead-Free Solder: Depending on the specific mix of metals, lead free will produce differing liquid, solid, and pasty range temperatures. Check with the solder manufacturers for these specifics.
-
- Keeping the tip clean is important but constantly wiping it on a wet sponge can cause early tip failure. Wiping causes the tip temperature to drastically rise and fall and the different metal layers in the tip to repeatedly expand and contract. This cycling leads to metal fatigue and ultimately tip collapse. The more frequently you wipe the tip, the more you stress it.
- Pushing the solder into the tip to force it to melt or rubbing the tip against the joint to force heat in will destroy the tip faster. Allow the iron to heat to the soldering temperature where normal contact of the solder with the tip causes the solder to melt.
- The lower the tin content of the solder, the more difficult it is to keep the tip from loosing its protective coating of solder (dewetting). Keep a roll of large diameter 63/37 on hand to periodically flush and re-tin your iron tip.
- Match the diameter of the solder to the tip. Using small diameter solders may not keep the tip flooded with solder while in use and cause the tip oxidize and wear faster. Use large diameter solder or periodically flood and tin the tip using large diameter 63/37 solder as suggested above.
- The more active the flux, the faster oxidation on the tip forms requiring more frequent tip cleaning. Using a flux with the lowest activity possible will help reduce oxidation and corrosion and maximize tip life.

Outlook "Operation has been cancelled" hyperlink problem
I am getting the Outlook 2003 "This operation has been cancelled due to restrictions in effect on this computer" hyperlink problem
GO here: http://www.dougknox.com/xp/file_assoc.htm and use the HTM/HTML association .zip.
Default Profile is being loaded instead of a user profile when user logs on
Computer booted up showing the desktop as it is when you first get the computer - all programes show on the start menu, (default profile is being used)
But look in My Documents & there 's nothing in the folder. All email profiles & info that I had on the desktop completely vanished.
Go into safe mode - just the same
If you look in the profile eg C:\User\thedukes0brent\docs - then all the files are there as expected, If you look on the profile desktop eg C:\User\thedukes0brent\desktop - then all the shortcuts etc are there.
So.......in effect the user account is there, but when you log on to it all settings & documents are not being accessed.
Solution:
In registry - HKLM\software\microsoft\windowsNT\currentversion\profile
- There are two folder enteries with the same id number, one ending in .bak & one without bak.
- The one without the .bak should have an entry for the profile and is pointing to a TEMP folder
- Swapping the .bak extension between the two folders, it points the profile back to the correct user folder
Prevent Code stripping in TinyMCE Editor
when you use certain code in TinyMCE it gets stripped when you save it.
Firstly make sure you have set Joomla's whitelist/blacklist thing properly as descibed in this article.
http://docs.joomla.org/Why_does_some_HTML_get_removed_from_articles_in_version_1.5.8%3F
The easiest way of checking this is to turn off your editor, paste some code in, save the article and see if joomla has stripped the code out.
Now you need to add some code for your selected HTML Tags in to the Valid Extended Elements field in Tiny Parameters.
Syntax is
tag[element1|element2|etc.],othertag[element1a|element2a|etc.]
Example
{code class="brush: xml"} {/code}
In this case, you can use the star which lets use any element.
object[*],param[*],embed[*]
You could limit what you authorize and add something like this
object[width|height],param[name|value],embed[src|type|allowscriptaccess|allowfullscreen|width|height]
Notes
- This method can be used for any specific tag one needs not to be cleaned.
- Parameter Tiny Clean Up on Save to "Always" as advised in the tooltip!
If you do, then Tiny extraneous mce_something stuff will remain in code, breaking email cloak. as mentioned on joomla forum - see here for fijiweb post
Is my server running phpSuExec
To determine if your server is running PHP via phpSuExec (i.e., CGI) instead of Apache
- upload a phpinfo() file and check the “Server API” near the top of the file.
- If it says “Apache”, PHP is running on Apache;
- if it says “CGI”, PHP is running via phpSuExec.
This is important because it is impossible to manipulate php.ini directives via htaccess while running PHP on phpSuExec.
How to create a PHP Info page
The PHP Info page is built into PHP and gives you vital information about your server.
- Create a blank PHP file
- add the following line to it.
{code class="brush: php"}{/code} - Upload the file to your webserver and then run it.
Reset permissions recursively via PHP
You can reset file permissions via PHP. the code below is an example on resetting file permission recursively. You must have shell_exec enabled.
- Create a blank php file
- Add the following code to it
<?php echo shell_exec( 'find . -type f -print0 | xargs -0 chmod 644' ); echo shell_exec( 'find . -type d -print0 | xargs -0 chmod 755' ); ?>
- Place the file in the root directory you want it to work from
- go to your webbrowser and execute the file
Windows XP Logs In Then Immediately Logs Off
You are unable to login to windows. It appears to work and then logs straight back out. This is usually because of a virus or malware that has been removed but the registry entery has not.
- Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\
- In the right pane, you might see something like
C:\WINDOWS\System32\wsaupdater.exe
- Change it so that it reads:
C:\WINDOWS\System32\userinit.exe
